php利⽤百度地图API进⾏IP定位和GPS定位最近在做⼀个⼿机端的webapp地图应⽤，⽽核⼼内容当然是定位了，但是定位的话有⼏种⽅式，IP定位,GPS定位，基站定位（这个貌似webapp⽤不了），那么剩下核⼼的gps定位和ip定位了，我们知道，html5有定位API，但是该API拿到的GPS数据是硬件坐标，⽆法直接显⽰在地图上。

后来上百度LBS云看到有地图IP定位API和GPS坐标转换API，地址：百度地图API的调⽤需要申请KEY，这⾥就不具体介绍了，直接贴上本⼈写了两个关键⽅法，为了⽅便前台调⽤，返回数据采⽤以下格式{address: "北京市海淀区西⼆旗北路",province: "北京市",city: "北京市",street: "西⼆旗北路",street_number: "",city_code: 131,lng: 116.3207676804,lat: 40.064084055578}核⼼类<?php/*** @author xialei <xialeistudio@>*/class map{private static $_instance;const REQ_GET = 1;const REQ_POST = 2;/*** 单例模式* @return map*/public static function instance(){if (!self::$_instance instanceof self){self::$_instance = new self;}return self::$_instance;}/*** 执⾏CURL请求* @author: xialei<xialeistudio@>* @param $url* @param array $params* @param bool $encode* @param int $method* @return mixed*/private function async($url, $params = array(), $encode = true, $method = self::REQ_GET){$ch = curl_init();if ($method == self::REQ_GET){$url = $url .

PHP通过IP获取地理位置（实例）发布：JB02 来源：脚本学堂【大中小】分享一例php代码，实现通过IP地址获取访问者的地理位置，在php编程中经常用到，有需要的朋友参考下吧。

PHP准确取得服务器IP地址的⽅法本⽂实例讲述了PHP准确取得服务器IP地址的⽅法。

分享给⼤家供⼤家参考。

具体分析如下：在php中，我们⼀般通过$_SERVER['HTTP_HOST']来活得URL中⽹站的域名或者ip地址。

php⼿册中的解释如下：“HTTP_HOST”当前请求的 Host: 头信息的内容。

⼀般来说，这样⼦不会遇到什么问题，在⼀些常见的php框架中，如PFC3和FLEA也是基于该预定义变量。

然⽽最近在做的⼀个项⽬，程序移交到客户⼿⾥测试时，竟然发现程序的跳转总是会出错。

最后找出原因：$_SERVER['HTTP_HOST']在客户的环境⾥，取得的值总是程序所在的服务器在其局域⽹内的ip值。

究其原因，是因为，客户的公司通过⼀台服务器连接⾄因特⽹，⽽我们的程序所在的服务器，是通过域名映射出来的，也就是中间有个“代理”的过程。

因此$_SERVER['HTTP_HOST']在这样的环境⾥，取得的值总是程序所在的服务器在其局域⽹内的ip值。

最后查了不少资料，在symfony框架⾥⾯，找到替代的实现⽅法:将复制代码代码如下:$host = $_SERVER['HTTP_HOST'];替换成：复制代码代码如下:$host = isset($_SERVER['HTTP_X_FORWARDED_HOST']) ? $_SERVER['HTTP_X_FORWARDED_HOST'] :(isset($_SERVER['HTTP_HOST']) ? $_SERVER['HTTP_HOST'] : '');希望本⽂所述对⼤家的php程序设计有所帮助。

php获取当前⽹址url并替换参数或⽹址的⽅法⼀是PHP获取当前页⾯的⽹址：复制代码代码如下://获得当前的脚本⽹址function GetCurUrl(){if(!empty($_SERVER["REQUEST_URI"])){$scriptName = $_SERVER["REQUEST_URI"];$nowurl = $scriptName;}else{$scriptName = $_SERVER["PHP_SELF"];if(empty($_SERVER["QUERY_STRING"])){$nowurl = $scriptName;}else{$nowurl = $scriptName."?".$_SERVER["QUERY_STRING"];}}return $nowurl;}另⼀个是PHP替换⽹址中query部分的某变量的值⽐如，我们要设$url中的key=321;其实有⼏种情况：$url='/a.php?key=330′;或$url='/a.php;或$url='/a.php?cat=2′;等等。

虽然情况很多，但PHP处理起来⾮常简单，如下：复制代码代码如下:/* 将URL中的某参数设为某值*/ //【这⼀段就挺好啊】function url_set_value($url,$key,$value){$a=explode('?',$url);$url_f=$a[0];$query=$a[1];parse_str($query,$arr);$arr[$key]=$value;return $url_f.'?'.http_build_query($arr);}不过我的替换是这样写的。

当然也很烂。

复制代码代码如下:<?php/***使⽤例程：可⽤于分页类或页⾯中的替换等$url = "add_jd.php?pid=4&tb=gm_jd&page=1";echo( "原始的URL：" . $url );echo( '<br/>' );echo( "字符串参数：" . url::replace( $url , "pid=10,page=2") );echo( '<br/>' );echo( "数组型参数：" . url::replace( $url , array('pid'=>10,'page'=>5)) );//echo( urlReplace( $url , array('pid'=>10,'page'=>5)) );*//*** url replace* @param string $url 需要替换的URL字符串，⼀般为aaa.php?abc=def,也可以带上路径，象/abc/def.php?aa=bb* @param mixed $options 需要替换的变量，可以是字符串或数组，如果是字符串，格式为"aa=bb,cc=dd"，有多个，⽤","隔开* @return string $url 替换后的URL*/class url{static function replace ( $url , $options){$options = self::optInit( $options );$Query = parse_url( $url , PHP_URL_QUERY );if($Query){parse_str( $Query , $GET );if ( $GET ){//foreach ( $GET as $_k => $_v ){// //if( array_key_exists( $_k , $options)){// $GET[$_k] = $options[$_k];// //}//}$GET = array_merge($GET,$options);}return str_replace( $Query , http_build_query( $GET ), $url );}if( !$Query && $options ){return $url . "?" . http_build_query($options);}return $url;}static private function optInit ( $options ){if( is_string( $options )){$optlists = Power::Normalize( $options );foreach( $optlists as $val){list($tmpKey,$tmpVal) = Power::Normalize( $val , "=");$opts[$tmpKey] = $tmpVal;}}else{$opts = $options;}//unset( $options );return $opts;}}虽然考虑了⼀些东西，但也仅仅是个很⼀般的解决⽅法以下是⼀些补充资料:例：我需要获取当前的的URL 地址$url_this = "http://".$_SERVER ['HTTP_HOST'].$_SERVER['PHP_SELF'];echo $url_this;则显⽰： http://localhost/lu.php服务器变量：$_SERVER注: 在 PHP 4.1.0 及以后版本使⽤。

PHP中实现获取IP和地理位置类分享发现之前有⼀个脚本没有写完，简单扩充了⼀下。

获取IP使⽤的是经典的逻辑，地理定位使⽤的是SINA的通⽤接⼝。

使⽤⽅法详见源码：复制代码代码如下:<?php/** GET LOCATION BY SINA IP INTERFACE** @SOULTEARY 2013.04.14*/classIP{private $args=array();function__construct(){$this->args=self::init_args(func_get_args());$ip=self::GetIP();$ret=preg_match_all('/(\d+\.){3}\d+/i',$ip,$result);if(!$ret){returnfalse;}else{$result=$result[0];}if(isset($this->args['ONLYIP'])&&$this->args['ONLYIP']==true){if(isset($this->args['FORMAT'])&&$this->args['FORMAT']=='JSON'){$result=json_encode($result);}else{$result=implode(',',$result);}if(isset($this->args['ECHO'])&&$this->args['ECHO']==true){echo$result;returntrue;}else{return$result;}}else{$apiURL='/iplookup/iplookup.php?ip='.$result[0];if(isset($this->args['FORMAT'])&&$this->args['FORMAT']=='JSON'){$apiURL.='&format=json';$return=$this->ipCURL($apiURL);}else{$return=$this->ipCURL($apiURL);$return=iconv("GBK//IGNORE","UTF-8",$return);}if(isset($this->args['ECHO'])&&$this->args['ECHO']==true){echo$return;returntrue;}else{return$return;}}}public functioninit_args($args){$result=array();for($i=0,$n=count($args);$i<$n;$i++){$result=self::associative_push($args[$i],$result);}return$result;}public functionassociative_push($arr,$tmp){if(is_array($tmp)){foreach($tmpas$key=>$value){$arr[$key]=$value;}return$arr;}returnfalse;}public functionGetIP(){if(isset($_SERVER['HTTP_X_FORWARDED_FOR'])&&$_SERVER['HTTP_X_FORWARDED_FOR']&&strcasecmp($_SERVER['HTTP_X_FORWARDED_FOR'],'unknown')) {return$_SERVER['HTTP_X_FORWARDED_FOR'];}elseif(isset($_SERVER['REMOTE_ADDR'])&&$_SERVER['REMOTE_ADDR']&&strcasecmp($_SERVER['REMOTE_ADDR'],'unknown')){return$_SERVER['REMOTE_ADDR'];}}private functionipCURL($url){$ch=curl_init();curl_setopt($ch,CURLOPT_URL,$url);curl_setopt($ch,CURLOPT_HEADER,0);ob_start();curl_exec($ch);curl_close($ch);$result=ob_get_contents();ob_end_clean();return$result;}}><!DOCTYPE html><html><head><meta charset="utf8"><title>demo</title><script type="text/javascript">varip="<?php new IP(array('ONLYIP'=>true, 'ECHO'=>true));?>";vardata=<?php newIP(array('FORMAT'=>'JSON','ECHO'=>true));?>;varresult='';for(oo indata){result+=oo+':'+data[oo]+"\n";}alert(result+ip);</script></head><body><h1>CODE:</h1><h2>GETIP</h2><p>'ONLYIP'=>true,'ECHO'=>true</p><p><?phpnewIP(array('ONLYIP'=>true,'ECHO'=>true));?></p><P>'ONLYIP'=>true,'FORMAT'=>'JSON','ECHO'=>true</P><p><?phpnewIP(array('ONLYIP'=>true,'FORMAT'=>'JSON','ECHO'=>true));?></p><h2>GET Location</h2><p>'ECHO'=>true</p><p><?phpnewIP(array('ECHO'=>true));?></p><p>'FORMAT'=>'JSON','ECHO'=>true</p><p><?php newIP(array('FORMAT'=>'JSON','ECHO'=>true));?></p></body></html>。
